Abstract
Cancer is an uncontrolled growth of a cell due to failure in the cell growth signaling system. Cure of cancer is done only by the complete removal of cancerous cells from the body, the process may sound simple but its implementation is almost impossible. There are number of problems regarding its treatment such as its early detection. Science is progressing every second and so are our expectations. This review is about present scenario and future promises about the development of biomarkers. It is a big challenge whose completion will be beneficial in the early detection of cancer. As early detection is half victory in any disease, especially cancer, this kind of research will be advantageous in the field of cancer treatment.
